I'm having gimbol lock issues in my space game. Is there a rotation command that does not use euler angles?

The matrices stored in the position data (on the sObject struct) look promising, but my half-blind attempts aren't getting me anywhere. It seems this should work:

+ Code Snippet

//...//
D3DXVECTOR3     p = parent->getDerivedPosition();
D3DXQUATERNION	q = parent->getDerivedOrientation();
sObject * obj     = dbGetObject(id_);

obj->position.bCustomWorldMatrix = true;
		D3DXMatrixRotationQuaternion(&obj->position.matWorld, &q);
obj->position.matWorld._13 = p.x;
obj->position.matWorld._23 = p.y;
obj->position.matWorld._33 = p.z;

But the result is a stretched and smushed spaceship. Setting matRotation and matTranslation didn't do anything.

Have you tried:

+ Code Snippet

dbTurnObjectLeft()
dbPitchObjectUp()
dbRollObjectLeft()

?

Pretty sure you will not have issues with these.
